The Mocal VR Series Roll Over Valve features an anodised coating for corrosion resistance and eye catching appearance.
The valve can be mounted vertically on the tank as a regular roll over valve which shuts off the tank breather (and therefore means of fuel escape) should the tank angle pass 90 degrees vertical. The valve can be used as a standard vent valve ideal for quick refuelling situations allowing the tank to 'breathe' and vapour escape without loss of fuel. The valve's by-pass is rated to 200mbar, which prevents pressure build up within the tank even in the event of a vehicle roll. The item is also FIA compliant providing you with peace of mind at scrutineering and on the event.
